In this paper we develop a statistical model of language complexity trade-offs using four typological measures (related to phonology, morphology, syntax and lexicon). The data come from the 100-language sample that appears in the World Atlas of Language Structures (WALS), and the trade-offs are...

This paper considers the portfolio problem for high dimensional data when the dimension and size are both large.We analyze the traditional Markowitz mean-variance (MV) portfolio by large dimension matrix theory, and find the spectral distribution of the sample covariance is the main factor to...

Some economists have argued that assortative mating between men and women has increased over the last several decades, thereby contributing to increased family income inequality. Sociologists have argued that educational homogamy has increased. We clarify the relation between the two and, using...

Many economic and financial time series exhibit time-varying volatility. GARCH models are tools for forecasting and analyzing the dynamics of this volatility. The co-movements in financial markets and financial assets around the globe have recently become the main area of interest of financial...

We examine Okun's Law on the basis of new growth perspectives and in the context of the WWWForEurope project. By comparing Okun's work from 1962 with the latest IMF and OECD surveys, a connection is set up and Okun's theoretical framework is updated and its persistence is examined. In addition,...

We investigate whether globalization influenced credit market deregulation over the period 1970-2010. Globalization is measured by the KOF indices of globalization. Credit market deregulation is measured by the credit market freedom indicators of the Fraser Institute. The results from both...

Estimates of the most common mobility measure, the intergenerational elasticity, can be severely biased if snapshots are used to approximate lifetime income. However, little is known about biases in other popular dependence measures. We use long Swedish income series to provide such evidence for...

This paper explores how inflows of low-skilled immigrants impact the tradeoffs women face when making joint fertility and labor supply decisions. I find increases in fertility and decreases in labor force participation rates among high-skilled US-born women in cities that have experienced larger...

We derive closed-form expressions for the performance measures(PMs)based on the lower partial moments (LPMs), such as the Farinelli-Tibiletti and Kappa measures, with Gram-Charlier (GC) density for returns. It is veriﬁed that the LPMs can be obtained as a linear function on both higher...

Estimates of the most common mobility measure, the intergenerational elasticity, can be severely biased if snapshots are used to approximate lifetime income.

Research questions: Main and first research question is to get a deeper insight into the relationship between the organizational culture (represented by the 4 main culture characteristics hierarchy, market, clan, and adhocracy), the leadership culture and "the outcome" of both towards the main...
